face 29 thereon. The inclination of the rear portion 21 is only slightand considerably less than the inclination of face 29 though extendingin the same direction.

The chair top 23 is of U-shaped configuration and hasarm portions 3! anda raised back 32. In the bottom of the chair top is a U-shaped recess 33conforming to and adapted to receive the U-shaped projection 25 of thechair seat, Fig. 6. The forward ends of the recess 33 have a downwardlyinclined surface 34 adapted to engage the surface 29 of the projection25 so that when the chair top is down upon the seat rearward tilt of thechair top is prohibited. Upon engaging the chair top over theprojection, the inclined faces 34 of the chair top recess 33 are firstengaged with the surfaces 29 on the front ends of the side portions 26of the projection 25 and then the chair top is pushed backwardly anddownwardly into place so that the recess receives the inclined rearportion 21 of the projection 25, Fig. '7.

The lower portion of the seat back 32 is de pressed to allow the recess33 to be inclined at the rear to accommodate the inclined rear portion21 of the U-shaped projection, Fig. 9.

In the rear portion 21 of the projection 25 there is a slot 35 midwayacross the portion 21 Fig. 10. This slot 35 is adapted to receive asecuring lug 36 on a pivoted latch 31 lying within a recess 38 in theback of the chair top, Fig. 10. This latch 31 has trunnions 39 adaptedto fit in half-circular sockets 4| at opposite sides of the recess. Inorder to locate the latch 31 within the recess and to place thetrunnions 39 in their sockets 4|, there is a removable plate 42 adaptedto be taken from the rear of the seat, Fig. 12. Once the latch has beendropped down into the recess 38, the plate 42 is secured in place byscreWs'eXtending through holes 43 at opposite sides of the plate. Uponthe inner face of the plate 42 are projections 44 and 45 havinghalfcircular sockets 46 aligned with the half-circular sockets 4| andadapted to fit over half of the trunnions 39 so as to complete thejournal connection of the trunnions with the back of the chair top.

In order to urge the lug 36 on the latch into the slot 35, there isprovided a leaf spring 41 on the rear face of the latch adapted tocooperate with the rear inner face of the removable plate 42. On theupper end of the latch 31 there is a button projection 48 adapted toextend through a hole 49 in the removable plate 42. When it is desiredto release the chair top from the projection, the button 48 is depressedagainst the action of the leaf spring 41 to disengage the lug 36 fromthe slot 35.

This chair top is made on its bottom edge to be smooth so that it can besafely located on a bed when removed from the chair seat and used as abed rest. The rear part is preferably upholstered but the arms and thebottom may be made of metal or plastic. The latch is well confinedwithin the recess 33 so as not to hinder the use of the rest upon thebed; The recess 33 is of such size as to easily accommodate theprojection 25. 7

By being inclined at the rear the removal and insertion of the chair topis facilitated.

While I have illustrated and described the preferred embodiments of myinvention, it is to be understood that I do not limit myself to theprecise constructions herein disclosed and the right is reserved to allchanges and modifications coming within the scope of the invention asdefined in the appended claims.

Having thus described m invention, what I claim as new and desire tosecure by United States Letters Patent is:
